1994 940 Volvo, with 213,000 miles. I've owned this car since 1998. I have replaced, or had replaced, a ton of stuff. I am interested in maintaining a sort of "cross the country" standard of reliability, in other words, a state of maintenance that will allow me to take off tomorrow on a long trip with my 5 year old son and expect reliable passage to and from our destination.

To ensure this, what parts should be replaced? I am speaking mostly of parts that can fail with no warning and leave one stranded, not those that will fail slowly with warning, such as say, a water pump.

A few items on my car are still original, such as the coil, the alternator, the starter. Should these start the list?

What is your "Replace for Reliability" list?

Thanks.
